To all whom t may concern.' I

Be it known that WILLIAM W. Bnin'nny, a citizen of the United Statesot America, residing at Detroit, in the county of l/Vayne and State of Michigan, have invented certain new and useful Improvements in Leaf- Spring Compressors, ot which the'following is a speciiication, ,reference being had therein to the accompanying drawings.

rIhis invention relates to leaf spring compressors and its object is to provide an attachment for a vehicle leaf spring to hold said spring under suiiicient compression during shipment of the vehicle to prevent activity of the spring during shipment due to movement of the conveyance in `which the vehicle is being shipped.

A further object is to provide a leaf spring compressor that may be very quickly attached to and detached from the 'vehicle spring and which will be positively restrained against any tendency to escape from the spring due to the expansive force of the latter and lto such stresses as may arise during shipment.

In the drawings: I

Figure 1 is a perspective view of the invention;

Figure 2 is a view in side elevation orf a semi-elliptic vehicle spring to which the invention is applied;

Figure 3 is a view similar to Figure 2 but showing the invention applied ,to a spring of the cantilever type.

In the construction shown in Figures l and 2, the reference characters A and B respectively designate two pivotally connected wire loops, the loop A being of a size adapt y ing it to be slipped over a sill C and. overa supporting vehicle leaf spring D while sa'id spring is temporarily subjected to any suit` able force placing it under compression, and of suiiicient strength to maintain the compression of the spring when relieved of said force. The loop B is proportioned to loosely' embrace the spring D andiorins an vanchorage member to restrain the loop A against shifting toward the convergent ends of the sill yand spring. This result the loop B accomplishes by engaging any suitably located projection on the vehicle, as for efr ample, one of the clip bolts E, whichattach the spring to the axle F. Pivotal connection between the two loops A. and B ispret'! erably established by forming pairs of eyes G at the adjacent ends of the two loops and engaging' said eyes by a bolt Gv. Prefu erably, the loop permit it tol assume whenengaging the compressed spring D so that, if by any sudden shock, said spring` is subjected to a greatercompression during shipment than that originally imposed thereon, said loop will tend to, swing labout its lower end so as tomaintain the increased compressionratherfthan tofrelease any of `the original compression. i

'To engage the loop B with said loop is detached `fromtthe loop A and its ends aresprung Aapart suiiiciently to pass at each side of the spring.

Referring now to the arrangement shown in Figure y l y porting a sill I, and attached aty its reduced end by clip bolts J to an axle K, having the underlying truss rod L. In applyingtlie invention to such a construction, the loop B is bent at a right angle, so that it may be hooked over the truss rod L aft-er the spring 'H has been sutliciently stressed to allow the loop A to establish a tie between the sill I and the reduced end of said spring as F igure` 3 clearly illustrates.

there is no necessity for, detaching the loops A and B from each other.

l hat I claim as my invention is:

l. A leaf spring compressor comprisingrv a tie member and an anchorageinember pivotally attached to said tie member, said members being respectively adapted for 3, H is a Acantilever springsupl In this instancel is, maarv A is, @f1 a. iength that `Win an inclined position v .thel spring, i

quick detachable engagement with a vehicle l spring and a relatively vehicle.

2. A leaf spring compressor comprising fixed portion of 'a a tie member forming a substantially closed loop proportioned to embrace a vehicle leafv spring and a sill of the vehicle, and an anchorage member attached to said tie inember for maintaining itsl engagement with said spring and sill.

3. A leaf spring compressor comprisingy a tie member forming a substantially closed loop proportioned to embrace a vehiclelea'f spring and ls-ill supported Vby saidspring, and an anchorage member adjustably' engagedl with one end of said tie member,

l". A leaf spring compressor comprising a tie member engageable with a sill :and-a supporting leaf spring o a vehicle to main--y tain .compression of said spring, and a looped anchorage member pivotally con-, nected to said tie member and'engageable Q Leeaeef chorage member pivotally attached to said tie member hooked for engagement with a part of the vehicle. n

e. A leafspring compressor comprising a pair of looped members one of which 1s proportioned 'to embrace a Vehicle sill and a leaf spring supporting said sill to maintain the springi under compression, the other being` proportioned to loosely engage the spring, the extremities of vsaid members forming coaxial eyes, and a bolt engaging said `eyes to establish a pivot-al lconnection between said looped members.

7. Vehicle leaf spring Compressor comprism@` tie member looped to embraee a leaf spring, and means Carried by the tie member 'for positif/elyrestraining the saine from shifting` longitudinallj,VT of 'the spring'.

8, Tin a` leaf' spring compressor comprising a pair of pivotallT connected loop members, one of which forms a tie member, and the ture.l n

other an anchorage member, said members being adapted by their loop for quick detachable engagement respectively with a Vehicle spring and a relatively fixed vportion 'i o a vehicle.

9. A lea-if spring Compressor Comprising a tie member having a terminal shoulder for respectively engaging a vehicle spring and a sill of a. vehicle, and an anchorage member pivotally secured to one end ofsaid tie member.

l0. l leala spring` compressor comprising1 pair or piv'otally connected loopy members, one of Which is proportioned. to embrace a vehicle sill and a leaf spring supporting said sill, to maintain the spring` in compression,

the other being to loosely engage the spring 'and constituting an anchorage member.

1]..The combination with a vehicle spring `and means mounting the same per-V manently upon an axle, of a compressor 'for said spring comprising a tie member, and an anchorage member pivotally attached to said tie member.
